Each of the following statements describes a quadrilateral. which of the quadrilaterals are not parallelograms? (pick 3) quadrilateral 1: the diagonals are congruent, but the quadrilateral has no right angles. quadrilateral 2: two consecutive sides are congruent, but the figure is not a rhombus. quadrilateral 3: each diagonal is 3 cm long, and two opposite sides are 2 cm long. quadrilateral 4: two opposite angles are right angles, but the quadrilateral is not a rectangle. quadrilateral 5: one diagonal is a perpendicular bisector of the other.

Quadrilaterals 1, 2 and 4 does not represents a parallelogram.

Step-by-step explanation:

We know that, a parallelogram is a simple quadrilateral that have two opposite sides congruent.

Now, according to the options:

1. A parallelogram does not have congruent diagonals without having right angles.

2. A parallelogram does not have consecutive sides equal without being a rhombus.

3. A rectangle is a parallelogram which have both the diagonals of equal length. So, this quadrilateral might represents a rectangle, which is a parallelogram.

4. No two opposite angles of a parallelogram are right angles without the quadrilateral being a rectangle.

5. A rhombus is a parallelogram which have both the diagonals bisecting each other perpendicularly. So, this quadrilateral might represents a rhombus, which is a parallelogram.

Hence, we see that options 1, 2 and 4 does not represents a parallelogram.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
